STORM WINDOW.

Application illedebruary 15, 1926. Serial No. 88,266.

My invention relates to storm windows and an object in general is toimprove the construction thereof. It is customary in cold climates toprovide what are knownas storm windows which are placed outside of theregular windows of the building. The storm windows commonly used consistof a frame which is suspended from the upper end so that whenventilation is desired,the storm window can be swung outwardlyat thebottom and held in this open position bymetal strips engaging the stormwindowv and the main window frame. n When thus opened, storm windows areapt to rattle and are frequently torn loose by high winds, andfurthermore, entrance of burglars is made an easy matter. I am awarethat it has been proposed'to provide storm windows with a lower portionwhich can be slid upwardly for ventilation, but so far as I am aware,all such prior constructions have been made in such manner that easyentrance for burglars is afforded when the storm window is opened forventilation. A particular object of my invention, therefore, is toprovide a storm window which is so constructed and arranged that it canbe opened suiiiciently tor ventilation without swinging the lower` endoutwardly and without providing an uncovered space through. whichburglars can enter the building.

The full objects and advantages of my invention will appear inconnection with the detailed description thereof, and the novel featuresot my inventive idea will be particularly pointed out in the claims.

In the accompanying drawings which illustrate.` one form in whichmyinvention 'g. 1 is an elevational view of the device as it appears fromthe inside of the building, and with the auxiliary window lowered. Fig.2 is a similar view showing the auxiliary window raised. Fig. 3 is asimilar view showing the auxiliary window entirely removed. Fig. 4 is anelevational view of the device as v Fig. 5 is a view in section ontheline 5-5 of Fig. 1. Fi 6 is a viewl in section on the line 6-6 of ig.l. Fi 7 is a view in section on the ig. 1. Fig. 8 isa view in section onthe line 8-8 of F 2. Figs. 5to 8 are on a larger scale than igs. 1 to 4.

Referring to the drawings, the numeral ates the frame of a storm windowwhich is adaptedto be secured in suitable vsure is insured in connectionmanner in the main window frame outside ot the customary sash. The frame10 is provided with an intermediate cross bar 12 and a lower crossbar'14. A pane of glass 16 is secured between the cross bar 12 and theupper member of the frame while another pane of glass 18 is securedbetween the cross bars 12 and 14. By referring to Figs. 7 and 8, it willbe noticed that the cross bar 12 is of the same thickness as thesurrounding framev and that the cross bar 14 is of reduced thickness onthe interior side of the window. Between the cross bar 12 and the bottomof the frame 10, the side members of the latter on their interiormargins are partly cut away to form `slideways 2O as best shown in Figsl 5 and 6 and these slideways are completed by securing metal anglestrips 22 to the frame members by screws 24. An auxiliary frame 26containing a pane of glass 28 is arranged to cooperate with theslideways and for this purpose, the side members of the auxiliary frameare rabbeted, as indicated at 30, .in order to be engaged bythe inwardlyextending anges of the angle strips 22. Itis obvious that the auxiliaryframe 26 may be inserted upon the slideways from the bo/ttom of the mainframe 1() and that it may be slid upwardly until the upper memberthereof engagesthe cross bar 12 as shown in Figs. 4

-2 and 8. It may be held in this upward position when Ventilation isdesired by means of hooks 32 lthereon which are adapted to engage witheyes 34 carried by the surrounding frame. When the weather is too coldto permit of ventilation with comfort, the auxiliary Aframe 22 is sliddownwardly into the position shown in Figs. 1 and 7 where it may be heldby engaging the hooks 32 with eyes 36 carried by the main frame 10. Inthis latter position, the upper member of the auxiliary frame fitsagainst the side of the cross bar 14 and the lower member fits againstthe side of the lower member of the 100 main frame 10 which it will benoted is of vreduced thickness to correspond with the thickness of thecross bar 14. When the frame 26 is thus secured, it is prevented fromdropping entirely down so that a tight clowith the main and atthe sametime the auxiliary frame fromthe window frame is held up somewhat vsillso that there is no liability of its freez- As best shown in Fig. 4, a110 ing fast thereto. frame 38 containing a\Wt1re screen 40 is securedto the outside o ooA he main frame 10 y between the bottom thereof andthefposition occupied by the cross bar 14 so as to cover the Ventilatingspace.

The operation and advantages of my invention will now be obvious. Theframe 10 may be secured in the window frame of the building in anysuitable manner. It may be conveniently hung at the top in the mannercustomary with storm windows now in use, and when fastened at the bottomon the inside cannot be lswung outwardly `by anyone on the outside. Theoperation'of the sliding frame 26 has already been referred to. When itis desirable to remove this auxiliary frame for cleaning the glass orwhen it is not desired to use the same in the summer `time,`the frame 10may be released at the bottom and swung outwardly whereupon theauxiliary frame may be readily slid o the bottom, and then the frame 10may be Whenmy device is used, it is impossible for burglars to readilyenter through the window, since the open space-.left by the raising orentire removal of the auxiliary frame is ordinarily too small for thispurpose, and the breaking of the glassl would almost certainly arousethe occupants of the building. Furthermore, this space is protected by awire screen secured in place, the cutting away or removal of which wouldattract attention.

I claim: K

1. A storm window comprising a main frame, an intermediate cross bar forsaid frame of Athe same thickness as the side members of said frame, apane of glass in the space above said cross bar, a lower cross barsubstantially midway between said intermediate cross bar and the lowermember of said frame, said lower cross bar/bein of reduced thickness andbeing flush witg the outer surface of said side members, a pane of glassin the space between said' intermediate cross bar and said lower crossbar .the space between said lower crossv bar an the lower member of saidmain frame again fastened in position. g

being open, slideways on the inwardmagms of said side members extendingbetween said intermediate cross bar and the lower portion ofthe mainframe, an 'auxiliary frame mounted' 'in said slideways, and a pane ofglass in said auxiliary frame, said auxiliary frame being disposed in avertical plane entirely outside said lower cross bar whereby saidauxiliary frame may be slid from lower position -in which the glasstherein closes said open space into upper .position with the upperauxiliary frame member in engagement with said intermedilate cross bar.I

2. A storm window comprising a main frame, an intermediate cross bar forsaid frame members of said frame, a pane. of glass in the space abovesaid cross bar, a lower cross bar substantiallymidway between saidintermediate cross bar and the lower member of the same thickness as theside 'of said frame, said lower cross bar and said lower frame memberbeing of reduced thickness and being flush with the outer surface rofsaid side members,

space between said intermediate cross bar vand said lower. cross bar,the space between said lowercross ba and the lower member of the mainframe b the inward margins of said side members extending between saidintermediate cross bar and the lower portion of the mainframe and lyingin a vertical 'plane outside of the aforesaid lower` frame member, anauxiliary ing open,slideways on'Y 'a pane of glass in the frame mounted`in said slideways, and a v pane of glass in said auxiliary frame, saidauxiliary frame bein disposed in a vertical plane entirely outsi e saidlower cross bar whereby said auxiliary frame may be slid from lowerposition in which the ,glass therein closes said open space into upperjposition with fthe upper auxiliary frame member in engagement Ywith saidintermediate cross bar.

In testimony vwhereof I hereunto allix my signature.
